CLOTH ROLL Filed Oct. 1 1953 JNVENTOR. LEONARD M. Eoezas ATTORNEY UnitedStates Patent 2,746,693 CLOTH ROLL I'eonard M. Rogers, Mention, Massassignorto Draper Corporation, Hopetlale, Mass, a corporation of MaineApplication October-1, 1953, Serial No. 383,611 '2 Claims. (cram-#74This invention pertains to cloth rolls such as may be used for windingfabric as it is taken up in a loom, and more particularly, to a part of:such rolls used to anchor or retain an end of the fabric as it isstarted to be wound on the roll. I

It is an object of the invention to devise a cloth roll,

preferably of metal, which shall be of small diameter,

Steel tubing with the fabric end retaining means integral therewith andproduced by a very simple machining step.

Other objects will become apparent from the following more detaileddisclosure.

Cloth rolls are employed in looms and other textile machines for use asa core upon which the cloth is wound and may be made from metal or wood.They have means for anchoring the fabric end so as to start windingafter which the tension on the material causes it to wrap tightly andthus to become self-energizing to an extent. Such means commonlyinvolves a slot and feather or other extra parts of such nature that theend cannot bedetached or the roll removed until the fabric is unwound.There have been some collapsible rolls used, but they are necessarily oflarger diameter and that detracts from the amount of material which canbe wound for any given case sincethe outside diameter of the package isdefinitely restricted.

According to the instant invention a roll of small diameter, that is,one just large enough to have theneeded rigidity is formed from solid ortubular stock, preferably the latter. Such a roll may be machined andprovided at its ends for receiving supporting gudgeons and for beingdriven positively as required. To hold the fabric end and yet permitready detachment and withdrawal of the roll, anchoring means in the formof pins are preferably integrally formed and are disposed slightlybelow, or at least, not above the cylindrical surface of the roll. Thesepins are inclined at an angle such that fabric impaled thereon will beheld as the roll is turned in a direction to Wind the cloth thereon.They are preferably produced with a hollow millingcutter which is fedinto the roll or tube at the required angle. In effect,

it counterbores the roll leaving at the center a projection or pin. Ifthe roll is a tube or hollow, the milling cutter is fed into the shellthereof and preferably through to the hollow interior at one side, butnot into the material at the roll surface at all at the other side. Thatis possible since the cutter is maintained at an angle such that the pinwill incline as required.

The invention will be described in greater detail in followingparagraphs wherein reference is made to the accompanying figures ofdrawing, wherein:

roll of Fig. 1.

Fig. 3 is a section taken at line 33, Fig. 2.

Fig. 4 is 'an end view of the roll.

Fig. 5 is a section similar to that of Fig. 3, but illustrating amodification.

Now referring to "Figs. 1, 2 and 3, the roll 10 showh here as a tube,preferably of standard tubing is cut to length and machined internallyadjacent its ends to accommodate bushings 11 and 12 within whichgudg'eons or other supports are to be received. At one and preferablyboth ends, a pin 13 is inserted and fixed, this pin being for thepurpose of transmitting driving torque to the roll and for use inreleasing and withdrawing the roll from the cloth.

A number of cloth retaining or anchoring means '14 comprise pins 15 andmeans defining an annular counterbore inset in the material of the roll.There may be as many of these cloth end retaining means as are required.All do not have to be used unless needed. The pins as herein shown arean integral part of the roll itself and are left by the machiningoperation which results in the counterbored opening 'or recess. Apreferred manner of forming the same employs a hollow milling cutter ofoutside dimension equal to the diameter ofthe counterbored recess whilethe hollow interior of the tool is of a diameter equal to that of the'pin, or at least, these figures are accurate when the cutting portionsof the tool are considered.

The angle at which the cutter is fed into the roll material, "that is,the angle of projection 'of the pins, is cohsiderably inclined to aradial plane through the pin. It may also be described as directed alonga line defining a segment of the tube or roll cross-section, which lineis positioned approximately within the middle third of a radius of thetube perpendicular to the segmental line. Thus the pins will incline ina direction to grip the cloth impaled thereon and to hold it moretightly as the roll is rotated; also, when the roll is turned reversely,the pins will withdraw from the cloth thus freeing the roll so it may bepulled endwise and removed. In this way the roll need not go along withthe cloth to be returned .but does not enter the material at theopposite side except to form the flat inset surface 17 from which thepin projects.

As shown in Fig. 3, the end of fabric F is pushed over pin 15 so thelatter pierces the fabric, this being done with the handle of a pair ofscissors or with any other suitable instrument. The fabric may be thusconnected to the roll at all or as many of the pins as are required toretain it for the first few revolutions after which the wrapping actionwill serve to prevent turning of the roll in the cloth.

When a roll of cloth of desired or maximum size has been wound, it isremoved in a known way and the roll may be removed by first rotating itreversely to release or withdraw the pins from the cloth and thenpulling it from the cloth. To do this a special tool may be engaged withone of the end pins 13.

The form of the invention described to this point con- 3 templatesinsertion of the roll in a loom or other textile apparatus so itsrotation will be directed as in Fig. 3. However, in Fig. 5 a roll 10 isshown in which there are two sets of pins 15 and 18 oppositely directedso ,that no matter how the roll is mounted one set of pins may be usedto grip the cloth end.

While the preferred form as herein illustrated utilizes steel tubing,the roll may be solid and may be of wood or other material. If of wood,the pins, of metal, must be driven or screwed into properly counterboredrecesses.

Likewise, with a metal roll the pins may be separately manufactured andinset in a convenient manner in counterbores in the metal. However, thatform herein shown and described is more economically produced and servesits intended purpose with a maximum of effectiveness.

While it is contemplated that the weaver use some :simple instrument toimpale the cloth end on the pins,

details described, but is intended to embrace all variations andmodifications thereof falling within the spirit of the invention and thescope of the claims.

I claim:

1. A cloth roll adapted to be rotated and to have fabric Wound thereoncomprising an elongated cylindrical member and means forming a partthereof to which an end of fabric may be anchored, but permittingremoval of the roll from cloth wound thereon which comprises pins ofcircular cross section disposed so that they do not project beyond thecylindrical surface of the roll and within counterbored recesses in theroll, said pins being integral with said roll and inclined at an angleintermediate a line tangent to the roll surface and a radial line bothof which intersect at the end of a pin, whereby as the roll is rotatedin one direction the pins engage the cloth more securely and whenrotated oppositely, they withdraw from and release the cloth.

2. A cloth roll adapted to be rotated and to have fabric wound thereoncomprising an elongated cylindrical memher and means forming a partthereof to which an end of fabric may be anchored, but permittingremoval of the roll from cloth Wound thereon which comprises a pluralityof spaced pins of circular cross section disposed so that they do notproject beyond the cylindrical surface of the roll, said pins furtherbeing centered within counterbored recesses in the material of the rolland inclincd at an angle intermediate a line tangent to the roll surfaceand a radial line both of which intersect at the end of the pin, wherebyas the roll is rotated in one direction the pins engage clothintentionally impaled thereon more securely and when rotated oppositely,they withdraw from and release the cloth.
